Hudson River Environmental Conditions Observing System

The Hudson River Environmental Conditions Observing System (HRECOS) is a network of near-real-time water quality and weather monitoring stations in the Hudson River Watershed. The stations are geographically distributed from Utica on the upper Mohawk River to the Hudson, down to the New York/New Jersey harbor. Stations record water quality and weather conditions every 15 minutes and transmit data in near real-time to the HRECOS website. HRECOS has a diverse user base consisting of researchers, resource managers, navigators, educators, and the general public.
